Application filed April 10, 1906, Serial No. 310,931. Renewed June 24,1909. Serial No. 504,018.

To all whom it may concern.'

Be it known that I, HENRY FRANCIS KEIL, a citizen of the United Statesof America, and a resident of Bronxville, in the county of Westchesterand State of New York, have invented a certain new and useful Look, ofwhich the following is a specification, the same being a full, clear,and exact descrip tion of the invention, -such as will enable thoseskilled in the art to which it apper tains to make and use the same.

My invention relates to appliances for securing in position doors andlike movable articles, and in particular to locks and latches adapted tobe inserted in a notch or recess in the stile of a door and having acombined escutcheon and face plate, and which embody certain novelfeatures of construction and combination and arrangement of partswhereby the lock is adapted to be applied to bevelededged doors, thesaid lock being ordinarily constructed with an expansible face plate andalso whereby the said lock is adapted to be operated by a manuallyactuated device, the whole being of simple construction and efficient inoperation, all of which will be hereinafter described and fullyillustrated in the drawino's.

tTo attain the desired end, this, my invention, consists in theconstruction, arrangement and operation of parts herein set forth.

In order to enable the invention to be fully understood I will proceedto explain the same by reference to the drawings, illustrative of oneembodiment of the invention, which accompany and form a part of thisspecification, and in which- Figure 1 represents a perspective view of alock constructed according to this invention having an adjustable faceplate; Fig. 2 is a vertical section taken on the line 5, 5, Fig. 4,showing the laterally enlarged orices in the escutcheons, Figs. 3 and lare sections through the line 6, 6, Fig. 2, showing, first,

the lock adapted to be partly applied to, and afterward fastened on bothsides of a beveled edged door, by reason of the laterally enlargedorifices in the escutcheons; Fig. 5 is a plan view of the lock shown inFig. l, and Fig. 6 is a detail of the face plate adjusting mechanism.

Like letters of reference indicate like parts in all the views.

Referring particularly by letter to the drawings, A, A1 denote mycombined escutcheon plates and face plate which rests against the sidesof a door and extends around its front edge, and preferably overlaps thenotch C, and which is preferably made of sheet metal. The combinedescutcheon plates A and face plate A1 is of a unitary construction, andso far as its func tion in supporting within the same the lock case D(which contains a suitable lock or latch mechanism) and in serving as acov ering for the notch or recess is concerned, may be considered as anentirety no matter whether it is integral and is ma de of a single pieceof metal, or whether it is composed of a plurality of plates rigidlyfastened to` gether, as shown in the present embodiment, in which theescutcheon plates A, which are ordinarily rigid in form and pref erablymade of cast metal, are secured to the extensions A2 of the preferablyiiexible and ordinarily sheet metal face plate A1.

B designates the knobs and B1 the shanks of the same which preferablyinclose the knob spindle and ordinarily pass through the preferablyloose knob roses B2 ordinarily supported on the knob shanks, and restagainst the sides of the lock-case D which is a complete article ofitself consisting of the body d and cap Z1 and is supported within thecombined escutcheons and face plate by means of screws cl2 inserted intothe front of the lock-case through the face plate A1. Y

The l0ck-case D is inserted into a recess, notch or mortise C formed inthe edge of the door, preferably by simply sawing a piece out to thedepth of the lock, and the top and bottom edges a, a', at (or, as itwere, flanges a, a* of the escutcheon plates, and extensions of thelock-face and edges a of the face plate) being of greater dimensions orsize than the opening or recess in the door, overlap the same, andthereby entirely cover or frame in the mortise and conceal any possiblepoor cutting out of the door, in the event of the same being carelesslyor hastily done. The top and bottomedges a, al a4 also serve to affordresistance flanges 0r borders or stops, in order to prevent any dangerof the lock from being pulled out of its position to any degree, or anylateral displacement thereof, or the bending or the straining of any ofthe parts inasmuch as the said edges a, a1 at rest respectively againstthe lllO sides and front edge of the door; the face plate A1 alsoserving to support the lockcase D.

The combinedescutcheons and face plate not only forms a protection -tothe wood of the door, but the said structure is very readily applied andquickly attached to the door by simply slipping the combined escutcheonsand face plate over the edge of the door and thereby inserting the lockin the notch or recess cut out of the stile and then screwing theescutcheons to the sides of the door in the proper applied position bymeans of the screws El.

This invention is applicable to all kinds of doors to which mortise orrim locks can be attached, and is manifestly applicable to both locksand latches, or a combination of the two.

I provide simple means for adapting my combined escutcheons and faceplate to be used for doors of different thicknesses, which preferablyconsists in making the same so as to be eXpansible and adjustable asregards the width of the face plate, as, in the present embodiment, byforming the same with a plaited or folded face plate, the folds orplaits a2 of the same ordinarily lying between the lock-case and theheads of the screws E. The shanks of the screws E work in threaded holesin the sides of the lock-case and may be operated by a tool inserted inthe orifices a3 formed in the extensions of the escutcheons, by whichmeans the adjustability or degree of expansion of the face Vplate may beregulated. In case the combined escutcheons and face plate is applied toa thin door, as in Fig. l, the seam between the folds a2 will be closed,but in the event of the structure being used in connection with andattached to a thick door, as often occurs, the folds a2 will be openedsomewhat (the screws E having been unscrewed) and after the combinedescutcheons and face plate is adjusted in position, the screws E may betightened so as to serve to hold, in connection with the escutcheonscrews El, the entire structure rigidly upon thedoor.

In some cases I prefer to construct the combined escutcheons and faceplate of such a width, when formed up, as will conform to a standardthickness of a door, and to that end the escutcheons are permanentlyheld a certain distance apart by the face plate which is fiXed in widthand not laterally eX- pansible, as shown in Figs. 3 and 4.

Iordinarily construct the knob roses B2 so as to be hollow or shell-likein form, the bores b3 of the same being larger in size than the diameterof the knob shanks, and the said knob roses being preferably fixed onthe knob shanks and slidable upon the escutcheon plates. The orifices A3formed in the escutcheon plates are also larger laterally than the knob`shanks to allow lateral movement of the latter within the escutcheonplates, which knob shanks are constructed and arranged to bear directlyagainst or lic adjacent to the lock hub.

In case the combined escutcheon plates and face plate is to be appliedto a beveled edged door, I first attach one of the escntch` eon platesto one side of the door, whereupon the face plate will not register withbut will stand a little distance from the said beveled edge, as shown inFig. I then force the other escutcheon plate inwardly until the fiexibleface plate registers with the said beveled edge, whereupon the lastnamed escutcheon plate may be screwed down to the door, as shown in Fig.4e. B reason of the laterally enlarged bores Z2 the roses B2 may bemoved laterally along the escutcheons and by-reason of the enlargedorifices A3 the lock case B and the knob shanks B1 which still remain inalineinent. are allowed to be deflected slightly without in any mannerimpairing the operation of the same, as is illustrated in Fig. Ll, thesaid orifices being covered and concealed by the roses B2.

The escutcheons being made of rigid and also thick material relative tothe face plate, it is manifest that if no laterally elongated orifice A3were formed in the same, shanks would bind in the escntcheons and couldnot be operated freely. This application diters in this respect from mycopending application filed contemporaneously herewith Serial No.301,930, where no lateral enlargement of the orifice in the ecutcheonsare necessary on account of the thin material of which the combinedescutcheons and face plate is made. In case one side of the edge of thedoor is beveled more than the other, or is rounded off, the saidorifices will permit the escutcheon on that side to be moved fartherbackward than the adjacent lock shank, in which case the knob shanks maynot lie parallel to the beveled edge of the door.

Two strips a5 are cut out from the top and bottom edges of each of thefolds or plaits a2, which strips are bent toward each other so as to liebehind the face plate and to present a practically unbroken edge of theface plate adjacent to, and above and below, the said folds.

In this application I claim only a combined escutcheons and face plateconsisting of a fiexible face plate and rigid escutcheon plates securelyattached to the same, together with the elongated openings in theescutcheons for the knob shanks, as the combined escutcheons and faceplate, per se, together with the other features of the inventiondisclosed, but not claimed herein, are claimed broadly in myapplications for patent filed April l0, 1906, Serial Nos. A310,929 and310,930.

the knob l etoe I wish it to be understood that I do not desire to belimited to the exact details of construction Shown and described, vforobvious modifications will occur to a person skilled in the art.

What I claim as my invention is- 1.. In a lock, a combined escutoheonsand face plate to rest against the sides of a door and extending aroundits front edge, a lock casing, knob shanks constructed and arranged tobe supported at right angles to the lock casing and to bear against thesame, knob roses each formed with a bore and being slidable on theescutcheons, and a latch mechanism inclosed by the lock casing, saidcasing adapted to be inserted in a notch in the door and supported bythe said combined escutcheons and face plate, the escutcheons havingorifices wider laterally than the knob rose bores and the bores of theroses being larger than the knob Shanks to allow lateral movement of thesame Within the roses, whereby one of the escuteheons may be applied toone side of a beveled edge door, and the face late bent to conform `tothe beveled edge o the door before the other escutcheon is fastened inplace without interfering with the working position of the knob Shanks.

2. In a lock, a pair of escutcheons, knob roses each formed with a boreand being slidable on the eseutcheons, the said escutcheons having aneXpansible face plate normally located at right angles thereto, a lockcasing supported thereby, knob Shanks constructed and arranged to besupported at right angles to the lock casing and to bear against thesame, the escutcheons having orifices Wider laterally than the knob rosebores, and the knob roses having bores larger than the knob Shanks topermit lateral movement of the same within the roses, whereby the saidescntcheons may be adjusted to a beveled edge door without interferingwith the working position of the knob Shanks.

In testimony of the foregoing specification I do hereby sign the same 1nthe city of New York, county and State of New York this second day ofApril, 1906.
